MIL-DTL-24788A
3.10.6 Strength. When tested as specified in 4.5.6, there shall be no damage which causes malfunctioning of
the semi-dry-break, quick-disconnect coupling assembly, nor shall there be any leakage exceeding one drop per
minute.
3.10.7 Angular movement. When tested as specified in 4.5.7, there shall be no damage which causes
malfunctioning of the semi-dry-break, quick-disconnect coupling assembly, nor any visible external leakage.
3.10.8 Endurance, wet and dry. When tested as specified in 4.5.8.1 and 4.5.8.2, the semi-dry-break, quick-
disconnect coupling assembly shall pass the operating force test and leakage tests, as specified in 4.5.8.1 and 4.5.8.2.
3.10.9 Electrical resistance. When tested as specified in 4.5.9, the electrical resistance across the semi-dry-
break, quick-disconnect coupling shall be less than or equal to 10.0 ohms.
3.10.10 Insulation breakdown. When tested as specified in 4.5.10, there shall be no insulation breakdown
either during or as a result of the test.
3.10.11 Accelerated corrosion. When tested as specified in 4.5.11, there shall be no evidence of corrosion
which might adversely affect subsequent operation of the semi-dry-break, quick-disconnect coupling assembly. The
semi-dry-break, quick-disconnect coupling assembly shall also pass the specified operating force, electrical
resistance, and insulation breakdown tests.
3.10.12 Rough handling. When tested as specified in 4.5.12, there shall be no leakage or physical damage that
causes malfunction of the semi-dry-break, quick-disconnect coupling assembly components.
3.10.13 Burst pressure. When tested as specified in 4.5.13, there shall be no evidence of leakage, distortion, or
failure of any component of the semi-dry-break, quick-disconnect coupling assembly.
3.10.14 Disassembly and inspection. After the requisite testing, the semi-dry-break, quick-disconnect coupling
assemblies shall be disassembled for inspection. There shall be no evidence of corrosion, wear, or distortion which
would adversely affect the performance of the assembly (see 4.5.14).
3.11 Cleanliness. When prepared for shipment, all components of the semi-dry-break, quick-disconnect
coupling assembly shall be free of dirt, manufacturing oils, and debris. There shall be no exposed sharp edges on
machined surfaces. Castings shall be free of blowholes. Mold parting seams shall be smooth.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a.
Qualification inspection (see 4.2).
b.
Conformance inspection (see 4.3).
4.1.1 Inspection lot. For the purpose of conformance inspection and test sampling, a lot is defined as all semi-
dry-break, quick-disconnect coupling assemblies and components of the same class, produced in one facility, using
the same production, processes, and materials, and being offered for delivery at one time.
4.2 Qualification inspection. Unless otherwise specified (see 6.2), qualification inspection shall be performed
on three complete semi-dry-break, quick-disconnect coupling assemblies, each consisting of a male half, female
half, and any necessary adapters required to conduct the qualification tests. The inspection shall include the
examination and the tests specified in Table I. A manufacturer may qualify either or both of the components; male
or female half of the semi-dry-break, quick-disconnect coupling assembly. In the event a manufacturer only
qualifies one of the two components, the non-test subjected items shall be a previously approved item under this
specification. Upon completion of qualification testing, any semi-dry-break, quick-disconnect coupling assemblies
used for qualification testing shall be clearly marked with the words "TEST UNIT" (or equivalent). Semi-dry-
break, quick-disconnect coupling assemblies used for qualification testing shall not be provided for any
procurement. The qualification test assembly(ies) may be a standard production item from the contractor's current
inventory provided the assembly meets the requirements of this specification and is representative of the design,
construction, and manufacturing techniques applicable to the remaining units to be furnished under the contract.
